Specification of Letters Patent.

Patented April 28, 1908.

Application filed June 6, 1907. Serial No. 377,625.

T 0 all whom it may concern:

Be it known that I, OswALD S. PULLIAM, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented certain new anduseful Improvements in Oar-Bol sters, of which the following is aspecifica tion.

My invention relates to improvements in car-bolsters and while I haveshown an embodiment of my invention in the form of a truck-bolster myinvention embraces a bodybolster construction as well.

The prime object of the present invention is to provide a simple andefficient construction employing end-members adapted to receive the endsof the top and bottom-members and cooperating with said members toreceive the thrust of one member and the pull of the other member.

To this end the present invention consists, of a car-bolster, in thenovel features of construction, and in the combination of parts all asfully herein described and claimed.

In the accompanying drawings which illustrate applications of myinvention, Figure 1 is a side elevational view partly in section of atruck-bolster embodying my invention; Fig. 2 a top plan; Fig. 8 a halfbottom plan view; Fig. 4 an end view; Fig. 5 a plan of an end-member;Fig. 6 an end view of endmember; Fig. 7 a side elevational view of anend-member; Fig. 8 a top plan of clip Fig. 9 an end view of same; Fig.10 a side elevational view of clip; Fig. 11 a broken side view ofconstruction showing a different form of endmember from that shown bythe form of Fig. 1; Fig. 12 a side view of an end-member of the form ofFig. 11 and Fig. 13 a plan of the same.

Referring to the drawings, the truckbolster, as illustrated and aspreferred, comprises a top-member 1 made of channel form. Secured to theupper face of the top-member is a center-bearing plate or member 2.

3 designates a bottom-member formed at each of its ends with ahooked-portion 4. The two members are joined at their centers by a kingpost 5. The respective ends of the top and bottom-members meet inend-members 6, and each end-member is adapted to have imparted theretothe pull of the bottommember and the thrust of the top-member.

In the drawings, I have shown two forms and the other of the form ofFig. 11. In both forms, the end-members are provided with a laterallyextending groove 7, having a contour corresponding with the contour ofthe hooked end portions of the top-member and adapted to receive thesaid hooked ends when the parts are assembled. The endmembers eachcomprise in addition to the groove 7, a body-portion 8, and abearingface or member 9. When the parts are assembled the body-portionextends under the respective ends of the top and bottom-members and theends of said members abut against the bearing-face 9. The end-membersare also provided with lugs 10 adapted to bear against the sides of thetopmember.

11 designate clips or engaging-members adapted to engage the ends of thetop-member. In the form of Fig. 1 clips 11 are made separate from theend-members and are secured thereto by rivets 12, while in the form ofFig. 11 the clips 11 are made integral with the end-members.

What I claim is: y

1. A bolster comprising a top-member of channel form, a bottom memberformed with an end hooked portion, an end-member provided with a groovecorresponding in contour with the hooked end portion and adapted toreceivethe same, lugs formed on the end-member, and said top-memberhaving the ends of its sides located between the lugs and the body ofthe end-member.

2. A bolster comprising atop-member, a bottom-member formed with an endengaging portion, an end-member provided with a groove adapted toreceive the end engaging portion, and a clip secured to the end-memberand engaging an end of the top-member.

3. A bolster comprising a top-member of channel-form, a bottom-memberformed with an end engaging portion, an end-member provided with agroove adapted to receive the end engaging portion, lugs formed on theend-member adapted to engage the sides of the top-member, and a clipsecured to the end-member and engaging an end of the topmember.

4. A bolster comprising a top-member of channel form, a bottom-memberprovided with end engaging-means, an end-member provided with means toengage an end of the bottom-member and having a bearing-face ofend-members, one of the form of Fig. 1 l in contact with an end of thetop-member,

lugs formed integral with the end-member, said top-member having the endof its sides located between the lugs and the body of the endmember.

5. A bolster comprising a top-member of channel form, a bottom-memberprovided with end-engaging-means, an end-member provided with means toengage an end ofthe bottom-member and havingabearing-face in contactwith an end of the top-member, lugs formed integral with the end-member,said top-member having the end of its sides located between the lugs andthe body of the the thrust of the top-member, and a clip engaging an endof the top-member.

In testimony whereof I afliX my signature in presence of two witnesses.
